OPERATING BASICS

SWITCHING POWER ON/OFF

Switch ON the DC power supply, then press and hold
down [POWER] until "HELLO" appears on the display.
Release [POWER] when you see "HELLO".

• After the "HELLO" message, the frequency and
other indicators appear.
To switch OFF the transceiver, press [POWER].
• After the transceiver has been switched ON, it can
then be switched OFF or ON by using only the
power switch on the DC power supply.

ADJUSTING VOLUME

AUDIO FREQUENCY (AF) GAIN

Turn the AF control clockwise to increase the audio
level and counterclockwise to decrease the level.

Note: The position of the AF control does not affect the volume of
"beeps" caused by pressing buttons nor the CW transmit sidetone.
Also, the audio level for Packet operation is independent of the AF
control setting.

RADIO FREQUENCY (RF) GAIN

Usually, set the RF control fully clockwise. If you are
having trouble hearing the desired signal due to
excessive atmospheric noise or interference from other
stations, it may help to reduce the RF gain.
To do this, take note of the peak S-meter reading of the
desired signal. Turn the RF control counterclockwise
until the S-meter reads the peak value that you noted.
Signals that are weaker than this level will be
attenuated. Reception of the station will be easier.
Depending on the type and gain of your antenna, and
the condition of the band, you may prefer leaving the RF
control turned counterclockwise by some amount
instead of turning it fully clockwise. When in FM mode,
always set the RF gain control fully clockwise.

SELECTING VFO A OR VFO B

VFO A and VFO B are modes that allow any desired
frequency to be selected within the frequency range of
the transceiver. VFO A and VFO B function
independently so that different or the same frequencies
can be selected for each VFO.
QUICK MEMO
Press [A/B] to toggle between VFO A and VFO B.
